Derek, Could you please log a JIRA bug and upload the sample code? Let's try to create the scenario on our boxes...

Thank you for the very fast response. >If possible please post us some numbers of the time comparison. Make >sure to avoid the System.out part when doing the comparison (this >encoding takes time :( )... First let me explain the setup. The two machines are identical hardware...Pentium 4 2.8GHz with 1Gig memory. Software differs since these are two different developer machines. Machine 1 acts as the client and is written in Java using Axis2. It sends an Excel file to Machine 2. When it receives the XML file back (see next paragraph) is simply saves it as a file. Machine 2 acts as the server and is using .NET. It receives an Excel file as binary, saves that file, uses an ActiveX control to read in the file and parse it to generate an XML representation of the data. It then sends that XML back to the Machine 1 in the SOAP response. I haven't written an isolated test but this setup would favor Java/Axis2 anyway since Machine 2 is having to do actual work in addition to reading the binary file. For smaller Excel files the times are quite reasonable. Test 1 -------------------------- For a 302K send and a 922K response. Time to send and receive response: 1.6 secs. Time to read response: 6 secs. It is taking about 3 times longer which is reasonable since the file size is 3x as large even though the server is doing a lot more work than the client. However, as the files get large the performance begins to break down. Test 2 -------------------------- For a 1.4M send and a 5.4M response. Time to send and receive response: 3 secs. Time to read response: 37 secs. 37 seconds to read the 5.4M binary file seems like a long time. As well you can see that the server processed a larger file (1.4M) in half the time as did the client in Test 1. For even larger files the difference becomes greater. Test 3 -------------------------- For a 8.5M and a 32M response. Time to send and receive response: 18 secs. Time to read response: 220 secs. Here you can see the .NET is reading the 8.5M (along with parsing it and generating XML) in 18 secs compared to where Java/Axis2 took 37 secs to simply read and save a 5.4M file in Test 2. I know this is an informal test case. But is 37 seconds to read a 5.4M binary attachment with no decoding similar to the experience of others? Thanks!
